NHGRI seeks next generation of sequencing technologies

...es" This group takes a stepwise approach to single nucleic acid molecule detection, using the nanoscale pore in a pulled glass pipette to measure single DNA molecules with attached nanoparticles. Understanding the electrical signals produced by, and the limits of this technology will contribute to next-gener...

Sniffing out the culprits of dust allergies

...all-molecule inhibitor was isolated from a peptide nucleic acid (PNA)-encoded small-molecule library. As a result of this investigation, Der 1 p was implicated in the cleavage of the CD4+ T cell receptor CD25--the Der 1 p inhibitor has a dose-dependent ability to protect the receptor on whole cells. This stu...

ASPB opposes proposed ban of GMOs in Humboldt county ballot measure M

...er, contrary to the Measure's definition, DNA is a nucleic acid and not a complex protein. This flawed definition in itself may make the proposed ordinance unenforceable. A review of the scientific literature shows that genetically engineered foods are safe to eat. For example, the National ...

Gene linked to greater risk of heart disease in type 2 diabetes

...re of the CD36 gene, which consists of hundreds of nucleic acids strung together like beads on a spiral necklace. They were looking for variants in this sequence that are associated with increased risk of heart disease. Studying 585 people who did not have diabetes, the researchers found five different CD36 ...

Upon graduation, the plants scientists will go on to work in the nation's botanical gardens, for the government and non-government organizations, as teachers in ...

Carnegie Mellon scientist develops way to deliver promising genetic tool into living cells

...to introduce a gene-like molecule called a peptide nucleic acid (PNA) directly into live mammalian cells, including human embryonic stem (ES) cells. The work, published online December 2 in Chemical Communications, http://www.rsc.org/is/journals/current/chemcomm/ccadvarts.htm , holds considerable promise in...

UT Southwestern researchers trace how virus that causes AIDS spreads following oral exposure

...is the first study to assess which tissues had SIV nucleic acid at the earliest times following an oral infection," said Dr. Donald Sodora, senior author of the paper. Oral transmission of HIV is problematic, especially in developing countries where bottle-feeding infants is not practical. Up to one third of...

New tuberculosis antibiotic may shorten treatment time, fight drug-resistant strains

...thesis, protein synthesis, folate biosynthesis, or nucleic acid replication. "Our compound is very different because it's the first antibiotic to my knowledge shown to be active against any bacteria by inhibiting their energy supply. The name DARQ was invented before we identified this mechanism, but you cou...

Novel technology detects human DNA mutations

...ential to markedly advance the state-of-the-art in nucleic acid and proteomic research and diagnostics." The analysis of whole human genomic DNA is extraordinarily complex as it requires sifting through the more than one billion base pairs of DNA to find a particular base pair of interest. Once that base pa...

Scientists document complex genomic events leading to the birth of new genes

...d at the nuclear pore complex, helping to regulate nucleic acid and protein traffic in and out of the nucleus. The corresponding gene is present in all sequenced animal genomes but not in other eukaryotes, such as plants or fungi. The new gene family characterized by Dr. Bork and his colleagues was largely ...

Basis for DNA ejection from single phage particles

...ed without directly contacting the membrane. Phage nucleic acid transport poses a fascinating biophysical problem: Transport is unidirectional and linear; it concerns a unique molecule the size of which may represent 50 times that of the bacterium. The driving force for DNA transport is still poorly defined....

Disease diagnosis, biodefense among UH chemical research projects

"We don't know of other remote methods capable both of detecting low levels of micro-organisms and visualizing high levels incorporated as biofilms or colonies," said Gregory Fisher, proje...

Bayer donates equipment to Children's Hospital, Oakland for infectious disease research

Also included with the gift are standard equipment needed for routine laboratory functions: microscopes, centrifuges, pipettors, electronic scales and power supplies. "The eq...

Neutralizing a protein linked to tumor development

...al as anticancer drugs. Aptamers - single-stranded nucleic acid molecules that are 50100 bases long and can be selected for their ability to bind directly and tightly to specific proteins - are less likely to be targeted and destroyed by the body's natural defenses than some other types of potential therapeu...

Microarrays as phenotype

Signs of aging: Scientists evaluate genes associated with longevity

...hypo-metabolic' state, which involved major lipid, nucleic acid, protein, and energy pathways, became less pronounced with advanced age. "We speculate that the apparent metabolic repression in early and mid-life adults contributes substantially to the observed longevity of daf-2," says Dr. Julius Halaschek-...

Biomarkers isolated from saliva successfully predict oral and breast cancer
